had a surveyer rasie a stink about a three position switch once, he said the auto portion should be wired hot all the time per code(don't know which code he was quoting). I would have to say, the majority of the boats I see with the three positon switch, the switch is left in the off position allmost all the time. I have two 2000 gph pumps in my V, each one plumbed with smooth wall 1 1/4 hose, each one with its own dedicated ground wire, float switch, inline fuse for the switch(may be changing to a breaker), and a separate line and power supply for the dash mounted switch. I keep a spare pump with aligator clips and 10' feet of hose in the cuddy for jic!
BTW, we've done the auto switch at the stop light before with a 34 Searay, it dumped about 10 gal of bilge water into a Chyrsler convertable at the light. At least it got here off the cell phone
